My dealer and parts department have no idea, and there seems to be no info out yet. On the 2020 I have seen, there is two coax style connections for the intellilink cameras right above the 7-way. All of the camera systems I see have a four pin connector to plug from the truck to trailer. I need to not only camera and wire up three trailers, but add the connections to a 14 Sierra with the Alpine restyle with extra camera inputs. Does the new truck come with a y cable that connects to the trailer wiring? Where do I get the connectors/wiring? EchoMaster has a terrible website for the OE system.
